How to connect two headphones to Xiaomi at the same time: all the ways 2026

Connecting two pairs of headphones to Xiaomi at the same time is a challenge faced by users who want to share music with a friend, use different devices to mix sound or just expand the capabilities of their smartphone. Unfortunately, not all models support the Dual Audio function out of the box, and in some cases require workarounds. In this article, we will discuss 5 proven ways to synchronously connect, including official functions, third-party apps and hardware adapters.

It is important to understand that the capabilities depend on the Bluetooth version in your device: Xiaomi with a Bluetooth 5.0 chip and higher (for example, Redmi Note 11 Pro, POCO F4, Xiaomi 13) have a better chance of successful implementation. Owners of older models (for example, Redmi 5 or Mi A2) will have to use alternative methods.

Before you start, check the Bluetooth version on your device: go to Settings → About Phone → MIUI → Full Specification. If your model supports Bluetooth 5.2 or newer, the chances of success are higher. Now let's get to specific methods.

Official Dual Audio function (for supported models)

Some Xiaomi smartphones based on MIUI 12.5 and later have a built-in Dual Audio feature that allows you to broadcast audio to two Bluetooth devices simultaneously, but it is not available on all models and can be hidden in deep settings.

To activate it:

• 📱 Open the Settings. → Connections and sharing → Bluetooth.
• 🔗 Connect the first pair of headphones (for example, Xiaomi Buds 4).
• 🎧 Click on the gear icon next to the connected device and select Additional Settings.
• 🔄 Turn on the Dual Audio option (or Double Audio) and plug in the second pair of headphones.

If you don’t have a Dual Audio, try an alternative route:

1. Activate Developer Mode (7 times click on the MIUI version in Settings → About Phone).
2. Back to Settings → Additionally. → For developers.
3. Find the option to Enable Dual Audio or Multithreaded Audio and activate it.

⚠️ Attention: On models with MIUI 13 and later feature may work unstable with headphones from third-party manufacturers (for example, Sony). WH-1000XM5 or JBL Live 660NC). In this case, the sound may be interrupted or lagged for 0.5-1 seconds.

2.Use of the SoundAssistant application (for all models)

If the feature is not built-in, Samsung’s official SoundAssistant app will come to the rescue, and although it’s designed for Samsung devices, it works well on most Xiaomi smartphones with Android 10 and higher.

Instructions for setting:

• 📲 Install SoundAssistant from Google Play.
• 🔊 Open the app and go to the Dual Audio section).
• 🎵 Turn on the option and connect two pairs of headphones via Bluetooth.
• 🔄 Set up the volume balance between devices with sliders.

The app allows you not only to broadcast the sound to two devices, but also to adjust the volume of each earphone separately, and also to turn on / off the microphone for one of them.

• ⚠️ Nana MIUI 12 and below may need to disable battery optimization for the application.
• ⚠️ Some users note a delay of up to 300 ms when using headphones with a codec AAC.

3. Bluetooth transmitters and adapters (for older models)

If your Xiaomi doesn’t support Bluetooth 5.0 or Dual Audio, you can use an external Bluetooth transmitter with multipoint function. Such devices (for example, the Avantek BTA-200 or 1Mii B06 Plus) connect to the smartphone via a 3.5 mm audio jack or USB-C and transmit a signal to two pairs of headphones at the same time.

Advantages of the method:

• 🎯 It works even on Xiaomi Redmi. 4X Mi 5 with Bluetooth 4.2.
• 🔋 Does not discharge the battery of the smartphone (powered by its own battery).
• 🎛️ Supports aptX Low Latency codec (minimizes delays).

Disadvantages:

• 💰 Additional costs (from 1,500 to 5,000 rubles).
• 🎧 The sound quality depends on the adapter (cheap models can distort high frequencies).

⚠️ Note: When using an adapter with a 3.5 mm connector on Xiaomi without audio output (for example, Xiaomi 12), you will need an adapter USB-C → 3.5mm Note that some adapters do not support digital audio transmission, which degrades the quality.

4. Multistreaming applications (SoundWire, AudioRelay)

If hardware solutions don’t work, you can use software workarounds through applications to transmit audio over a local network, for example, SoundWire or AudioRelay allow you to stream audio from Xiaomi to another device (for example, a second smartphone or PC) to which the headphones are connected.

Step-by-step instructions for AudioRelay:

1. Install AudioRelay on both devices.
2. On the main smartphone (Xiaomi), select the Sender.
3. On the second device, select Receiver and connect the headphones.
4. Run the live stream in the app on Xiaomi.

Pros of the method:

• 🌐 It works via Wi-Fi or mobile internet (without Bluetooth).
• 🎚️ You can adjust the sound delay (useful for watching videos).

Cons:

• 📶 Requires a stable connection to the network (with a weak signal will be lags).
• 🔋 Increased battery consumption on both devices.

💡

If the sound is interrupted, try switching from Wi-Fi to a mobile hotspot – sometimes this reduces latency.

5. Rooting and Modifying System Files (for Advanced)

For users with unlocked bootloader and root rights, it is possible to manually activate Dual Audio through system file editing, a method suitable for models where the function is blocked by the manufacturer, but hardware support is available.

Instructions (requires TWRP and Magisk):

1. Install the Magisk Bluetooth Dual Audio Enabler (available on the XDA Developers forum).
2. Reset the device.
3. In the file manager with root rights, open /system/build.prop.
4. Add the line: persist.bluetooth.dualaudio=true
5. Save the changes and restart the smartphone.

Risks of the method:

• 🚨 Loss of warranty (when unlocking the bootloader).
• 🐛 Possible Bluetooth malfunctions (for example, headphones shutdowns).
• 🔄 After updating MIUI settings may reset.

Comparison of methods: which one to choose?

The choice of method depends on your Xiaomi model, budget and technical skills. Below is a comparison table with recommendations:

For most users, the best solution is SoundAssistant or an external Bluetooth adapter. Owners of flagship models (Xiaomi 14, POCO F5 Pro) should first check the built-in Dual Audio feature. If you need a professional solution without delay (for example, for watching movies), consider an adapter with support for aptX Low Latency.

💡

On models with MIUI 14 and HyperOS, the Dual Audio function can be called Multiaudio and is located in the Special Features section.
